Variation of Effective Surface Emissivity with Angle and Implications for Clinical Thermography

Abstract

INFRARED scanners1 now find considerable application in clinical thermography. The image is interpreted in terms of differences in surface temperature, and local variations in apparent temperature of 2° C have been regarded as possibly indicative of pathology in, for example, attempts at early detection of breast cancer2. The energy received by the detector… (More)
